The composition method from [1]} can be used to show that certain other classes \(\mathcal {A}\)  of graphs are smooth; and for a class
\(\mathcal {A}\)  which is smooth we can prove results like those presented above, in particular like Corollary REF  (with wvhp  weakened to whp), Theorem REF , and Corollaries REF  and REF . This approach naturally yields also other results concerning for example the typical size of the core.
